You're joking, of course. You can't even get an approximate measure of
your
receiver sensitivity/noise floor from that test. Suppose, for example, that
an
active electrical storm is brewing and you're tuned to a 40M QRG. All but
the
most stone-deaf receivers will give you some room-filling background noise
which
will disappear when the antenna is removed.

Isn't that just a tad on the "Captain Obvious" side Hans?

Apparently not to Jim.
